From: Colorimetric detection of individual biothiols by tailor made reactions with silver nanoprisms
Sensitivity of AgNPR-based biothiol detection system. (1) Absorption spectra and corresponding photograph images and (2) the reciprocal absorbance at 416 nm in the presence of (a) Hcy, (b) Cys, and (c) GSH at varying concentrations (0–10 µM) in 1% human serum (pH 7), respectively. In (2), the calibration curves with the linear equation, and the tables showing standard deviation (SD) of the blank sample, slope of the linear calibration curve, and limit of detection (LOD) for (a) Hcy, (b) Cys, and (c) GSH, respectively, are inserted.
